Description

Förderanlage mit wahlweise durch den Fördergutträger einstellbaren Weichen mittels Lichtstrahls Zur trägheitslosen Beinflussung von Steuereinrichtungen durch den fahrenden Fördergutträger werden bekanntlich an der Fahrbahn lichtelektrische Zellen angeordnet, deren Belichtungsänderung durch den Fördergutträger den gewünschten Steuervorgang, wie z. B. die Einstellung einer Ablenkweiche; auslöst. Wenn nur bestimmte Fördergutträger die Ablenkweiche verstellen sollen, so müssen die Fördergutträger 'LTnterscheit.lungsmerkmale tragen, die nur in den Steuerstellen.. eine Wirkung ausüben, in denen die Merkmale des Fördergutträgers mit den Merkmalen der Steuerstelle übereinstimmen. Zu diesem Zweck ist es bekannt, an Rohrpostbüchsen in bestimmten Abständen mehrere Einkerbungen oder auch Spiegel vorzusehen und an jeder Steuerstelle Lichtquellen und lichtelektrische Zellen in bestimmten Abständen zueinander anzuordnen. Mit Hilfe einer besonderen Schaltung ist dafür gesorgt, daß nur dann ein Steuervorgang ausgelöst wird, wenn alle lichtelektrischen Zellen der Steuerstelle gleichzeitig eine Belichtungsänderung erfahren, d. h. wenn die Abstände zwischen den Lichtzellen mit den Abständen der Einkerbungen oder Spiegel auf der vorbeifahrenden Büchse übereinstimmen. Diese Steuerungsart erfordert an jeder Steuerstelle eine Mehrzahl von Lichtquellen und Lichtzellen. Außerdem ist eine besondere Hilfsschaltung erforderlich, durch die die gleichzeitige Belichtungsänderung .der Lichtzellen aasgeprüft werden muB.Conveyor system with optionally adjustable by the conveyed goods carrier Switches by means of a light beam For the inertia-free influencing of control devices As is well known, the moving goods carriers are photoelectric on the roadway Arranged cells, the change in exposure of which by the conveyed goods carrier the desired Control process, such as B. the setting of a deflection switch; triggers. If only certain Conveyor carriers are to adjust the deflection switch, the carriers must 'LT failure features that only have an effect in the control stations exercise in which the characteristics of the carrier with the characteristics of the control station to match. For this purpose it is known to use pneumatic tube carriers in certain Several notches or mirrors should be provided at each control point To arrange light sources and photoelectric cells at certain distances from one another. With the help of a special circuit it is ensured that only then a control process is triggered when all photoelectric cells of the control unit are activated at the same time experience a change in exposure, d. H. when the distances between the light cells match the spacing of the notches or mirrors on the rifle passing by. This type of control requires a plurality of light sources at each control point and light cells. In addition, a special auxiliary circuit is required through which the simultaneous change in exposure of the light cells must be checked.

Bei der Erfindung dagegen werden mehrere Lichtzellen an der Steuerstelle und die Schaltmittel für die Gleichzeitigkeitsprüfung entbehrlich. Es genügt eine einzige Lichtzelle. Erreicht wird diese Vereinfachung dadurch, daß ein Lichtstrahl über zwei einstellbare Spiegel auf ein lichtempfindliches Element trifft.In the invention, however, several light cells are at the control point and the switching means for the simultaneity test can be dispensed with. One is enough only light cell. This simplification is achieved by the fact that a light beam hits a light-sensitive element via two adjustable mirrors.

Als Ausführungsbeispiel ist in der Abbildung eine Rohrpostanlage angenommen worden, in der die Rohrpostbüchsen auf die verschiedenen Empfangsstellen eingestellt werden können. Zu diesem Zweck ist jede Rohrpostbüchse B mit einem festen Spiegelring S 1 und einem verschiebbaren Spiegelring S= ausgerüstet. Durch den Abstand a der beiden Spiegel voneinander ist das Ziel der Büchse gekennzeichnet. Stimmt nämlich der Abstand d mit dem Abstand zwischen den Schlitzen 311- und :i12 überein, so wird bei Vorbeifahrt der Büchse, die auf diese Steuerstelle eingestellt ist, der von der Lichtquelle L durch den Schlitz 311- auf den Spiegel S1 fallende Lichtstrahl über den Spiegel S2 auf die lichtelektrische Zelle L E geworfen. Durch die hierdurch bedingte Widerstandsänderung der Zelle LE wird das im Anodenkreis des Audions A liegende Relais R wirksam. Durch Anwendung der Audionschaltung bleibt trotz der kurzzeitigen Beeinflussung von LE der Kontakt r des Relais R so lange geschlossen, daß mit vollkommener Sicherheit der Weichenmagnet IV11 anzieht, der die Fahrrohrweiche umlegt, über die die Büchse zur Empfangsstelle fährt. Der Magnet W11 hält sich über seinen eigenen Kontakt ulzsa so lange. bis die Büchse bei Einfahrt in die Empfangsstelle den Kontakt e öffnet. Die durch Schlitze 311 und 111? gekennzeichnete Einflußstelle an der Fahrstrecke ist in entsprechender Entfernung vor der zu steuernden Weiche angebracht.As an exemplary embodiment, a pneumatic tube system has been assumed in the figure, in which the pneumatic tube boxes can be set to the various receiving points. For this purpose, each pneumatic tube carrier B is equipped with a fixed mirror ring S 1 and a sliding mirror ring S =. The target of the rifle is marked by the distance a between the two mirrors. True namely the A opening gap d with the distance between the slots 311- and: i12 match, then, the falling of the light source L through the slot 311- on the mirror S1 light beam on the passing of the sleeve, which is set to these controls via the mirror S2 thrown onto the photoelectric cell LE. Due to the change in resistance of the cell LE caused by this, the relay R located in the anode circuit of the audion A becomes effective. By using the audio circuit, the contact r of the relay R remains closed despite the short-term influence of LE so long that the switch magnet IV11 attracts with complete certainty, which folds the travel pipe switch over which the bushing drives to the receiving point. The magnet W11 lasts so long through its own contact ulzsa. until the socket opens contact e when entering the receiving point. The through slots 311 and 111? The marked point of influence on the route is attached at a corresponding distance in front of the switch to be controlled.
